So, it seems to be a NM problem after all.

HAL added a new bus type (ssb) in [1], which NM doesn't cope with (yet)

NM upstream has to say the following:

<mbiebl> got more info on the b43 prob
<dcbw> mbiebl: ok
<dcbw> mbiebl: did I ever get an lshal for ssb ?
<mbiebl> http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=540613
<mbiebl> http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=540613#48
<mbiebl> One difference is, that with old hal, rfkill-input is loaded
<dcbw> mbiebl: if it doesn't show up in 'iwconfig' or the module doesn't get
autoloaded, that's more of a kernel/driver problem
<dcbw> mbiebl: that's odd
<dcbw> mbiebl: I wonder what does that...
<dcbw> mbiebl: fun
<dcbw> I think the HAL ssb patch is, well, flawed
<dcbw> first off, the 'ssb' bus is *always* owned by a specific hardware device
<dcbw> it's on a PCI card, and it includes a PCI <-> SSB bridge as part of the chip
<dcbw> thus, the ssb bus is a child of that PCI card (or USB)
<dcbw> I read the lshal wrong, forget that
<mbiebl> It's interesting to compare the diff between the old and new hal
<mbiebl> dcbw: why does NM not find a device driver, btw
<dcbw> mbiebl: because ssb is a new bus, and since the 'driver' key isn't on the
device itself, but a parent the device, we have to walk around the device list
and find it, and that's different for every bus type
<mbiebl> /org/freedesktop/Hal/devices/pci_14e4_4312 has info.linux.driver =
'b43-pci-bridge'
<dcbw> mbiebl: right, but info.bus == ssb for wlan0
<mbiebl> dcbw: so it is a bug/missing feature in NM then?
<dagger> similar to http://bugs.gentoo.org/show_bug.cgi?id=279104 ?
<dcbw> mbiebl: yes, it's a bug in NM, but it's caused by HAL changing behavior
pretty dramatically
<dcbw> mbiebl: HAL added the 'ssb' bus, and thus the device list no longer has
the same relationships between devices that we had expected
<dcbw> ewoerner: how much time would it take?
<ewoerner> dcbw: i just hat 5 seconds (admittedly, i had some serious swapping
problems at that time)
<dagger> mbiebl: dcbw: I had a similar bug report with suggested patch, but I
didn't have time to look at it yet.
http://bugs.gentoo.org/attachment.cgi?id=199167&action=edit
<mbiebl> dcbw: interesting that you haven't seen this issue show up in fedora
<dcbw> mbiebl: we're in the process of getting rid of HAL, not udpating it :)
<mbiebl> which hal/nm version do you ship there?
<dagger> 0.7.1 (with some extra patches backported from 0.7 branch) + hal 0.5.13
<dcbw> mbiebl: F12 will have 0.5.13
<dcbw> mbiebl: F11 (current release) ships 0.5.12
<dcbw> mbiebl: but in F12, NetworkManager 0.8 doesn't use HAL anymore
<dcbw> dagger: patch doesn't apply to current 0.7 branch of course, but I think
I've got something that will work there



Cheers,
Michael
